Rumors tell of a Stony Cat statue that grants a special wish: it will take one of your disliked personality traits and give it to someone in need. Two students arrive at the Stony Cat eager to make a change – Youto, an unabashed pervert, wishes to remove his façade and be able to speak his true feelings, while Tsukiko desires to hide her expressions and be more like an adult. However, little did the pair know that their prayers would be answered in unexpected ways – Youto begins to speak the full, embarrassing truth with brutal honesty, and Tsukiko becomes visually stoic, unable to smile, laugh or cry! To make matters worse, Youto soon runs afoul of the beautiful school idol Azusa, the girl who inherited his unwanted façade. Together, the three slowly become friends while Youto and Tsukiko try to regain what they've lost.
